In your opinion what does it mean to be atheist?

I believe that many people get confused about the term "Atheist." Is an Atheist just a person who doesn't believe in a supreme being or is there more to it? How does one become Atheist? What is it like be in a world that is dominated by religion? Please give me your feedback on this topic. Help me gain insight on the Atheist community so to speak.

In my own humble opinion, what term means is a person who does not believe in (is not convinced of) the existence of god(s). I have seen this usage about as frequently as the slightly stronger one, which holds that atheism means belief (conviction) that there is/are no god(s). It is a small but vital difference.

Many Christians would have you believe that it means someone who believes in god but denies it, or someone who hates god or, in some extreme cases, a Satanist.
